Today is National Dolphin Day, but we love them all year round. Dolphins are one of the most beloved creatures in the sea. These marine mammals are smart, charming and downright adorable. Today, we are focusing on some of the many different dolphin species that call the ocean home. Join us in celebrating National Dolphin Day by exploring just a few of the coolest dolphin species known to man!

Atlantic Spotted Dolphins

Atlantic spotted dolphins aren’t born with their trademark spots. Newborn calves are gray with white bellies and through adolescence, they change into two-tone dolphins with only some spots on their belly. As they get older, they develop more and more spots all over their body. You could say that Atlantic spotted dolphins’ freckles are their version of wrinkles!

Spinner Dolphins

Ever see a dolphin leap into the air and do multiple barrel rolls mid-flight? Well, if you were lucky enough to have that experience, you probably saw a spinner dolphin. These dolphins are known as the acrobats of the ocean. They use their spinning skills to communicate, clean themselves or just to have some fun.

Dusky Dolphins

Dusky dolphins can be found in coastal waters of the southern hemisphere. They are usually located off the coasts of Africa, New Zealand and South America. These marine beauties prefer shallow waters not exceeding a mile in depth. If you are lucky enough to see a dusky dolphin, you will probably encounter a large number of them! They travel in pods of up to thousands of individuals.

Pilot Whales

Did you know pilot whales aren’t just whales? Pilot whales are dolphins, too! They are the second largest dolphins behind orcas. There are two species of pilot whales, short-finned pilot whales and long-finned pilot whales. Both look similar except for the distinguishing difference in length of their flippers. Pilot whales are highly social mammals. They travel in pods up to 100 individuals. Pilot whales even socialize with other dolphin species!

Striped Dolphins

Striped dolphins are some of the most curious dolphins out there. They are known to ride up close to boats in search of adventure. Their behavior at the surface of the ocean is a feat of nature. Striped dolphins have been recorded leaping up to 20 feet into the air! One of the reasons they can reach this height is due to “roto-tailing.” Roto-tailing is when a dolphin vigorously pumps its tail even when airborne!

Clymene Dolphins

Clymene dolphins were thought to be a subpopulation of spinner dolphins for many years. Then in 1981, clymene dolphins were granted the classification as a separate species. The best way to identify the difference in the wild is to observe their behavior and facial marks. Spinner dolphins and clymene dolphins share many physical characteristics, though clymene dolphins have slightly shorter beaks than their close relatives.

Hourglass Dolphins

Hourglass dolphins are one of the most fashionable dolphins in the sea. These dolphins are smaller in size and have high-contrast black and white striped patterns along their sides. Their flippers are unique as they sharply curve down their body. Their beaks are very short and stubby, making these dolphins look similar to the critically endangered vaquita porpoise. Hourglass dolphins are extremely unique which make them more lovable!

As you know, dolphins are pretty awesome. Sadly, marine debris can threaten all species of dolphins. But, if we work together and make small changes in our daily lives, we can protect these awesome animals from the danger of marine debris. Join Ocean Conservancy in the fight against ocean trash and sign up for the International Coastal Cleanup. This fall, join thousands of volunteers around the world cleaning up beaches and waterways to make the ocean a better, safer home for dolphins. Check out our clean up locations this summer to find a cleanup near you! Want to get started now?
